I don't have a multimeter to check the voltages but ASUS PCProbe records the voltages at 4.95 and 12.22 while PC Wizard 2008 recorded them at 4.95 and 11.61.
You may have overstressed that marginal power supply, once they have been pushed too hard they never recover.
You seemed to have covered most of the more likely scenarios.
What are the 12 and 5 volt rails readings?

Yeah I forgot to mention that I'd been watching the temps. The CPU and mb have stayed both below 50°C but I haven't been able to watch the graphics cards as easily. I took the following picture at idle and will post the results to memtest86+ tomorrow. Let me know if you want any other info.
I would install Ultimate Boot CD and run memtest86+ for 6 hours minimum, and post the results if you could.
I would then install PC Wizard and post the temp. and voltage screen, if you would.

The cards don't have a power connection on them. All the power is ran through the board with a legacy connector on the mb.
the 12 volt rail may be weak, do those 7600GT's have an option for direct power or is it all coming from the pci-e slot?
seperating the 2 12 volt rails might be an option(rearranging power cables)
It would be nice to have a premium 3 12 volt rail PS to test with?
Another thought have you benched each card running by itself with 3dmark or another program?
with 1 card the minimum is 400 watts but 550 watts for sli according to nvidia

I let memtest86+ run for 9.5 hours and here is the summary:
the video cards are running a bit hot for no load, and I do see hints of not enough power getting to everything.
I would recommend you upgrade the PSU to a minimum of 600watts.

Is there any connection between these problems?

All of those connections are secure.
okay, the board needs the following power plugs to be completely filled and snugly connected. I need to know that that is indeed what you have done.
1. 24 pin main (right above the floppy plug)
2. the 4 pin 12v rail (next to the heat sink behind the rear panel plugs)
3. the molex connector (next to the blue PCIex slot)
